11LC010-E/SN

Overview

The Microchip Technology 11LC010-E/SN is a 1 Kbit (128 x 8) serial electrically erasable PROM utilizing the UNI/O single I/O bus interface. It operates within a supply voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 100 kHz. The device features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce. It offers high reliability with 1,000,000 erase/write cycles endurance and data retention exceeding 200 years. The component is housed in an 8-lead SOIC package and is rated for an extended temperature range of -40°C to +125°C.

Feature Summary

• Supports the patented UNI/O single I/O serial bus protocol using Manchester encoding on the SCIO pin.
• Includes built-in write protection mechanisms such as power-on/off data protection circuitry and a write enable latch.
• Features a 16-byte page-write buffer for efficient data storage operations.
• Provides block write protection allowing configuration to protect none, one-quarter, one-half, or all of the memory array.

Applications

• Microcontroller system data logging
• Configuration parameter storage
• Calibration value retention

Procurement Notes

Verify that the ordering suffix 'E' corresponds to the Automotive temperature grade (-40°C to +125°C) rather than the Industrial grade. Confirm the 'SN' suffix indicates the 8-lead SOIC package type. Ensure the specific revision level matches the design requirements, as datasheet revisions may impact electrical characteristics or timing parameters.

Selection Notes

Select this part when a single-pin serial interface is required to minimize PCB trace count. The UNI/O bus eliminates the need for separate clock and data lines. Choose the Automotive grade variant if the application environment exceeds standard industrial temperature limits. Verify that the 1 Kbit capacity meets the non-volatile storage needs without requiring larger density devices.

Part Context

This component belongs to the 11XX family of 1 Kbit through 16 Kbit Serial Electrically Erasable PROMs from Microchip Technology. The family shares common architectural features including the UNI/O interface and similar command sets, differing primarily in memory density and operating voltage ranges between the AA and LC series variants.

Replacement Considerations
